Abstract

La presente está relacionada con un mecanismo limitador que es adecuado para un dispositivo de inyección, especialmente un dispositivo de administración de fármacos de tipo bolígrafo. El mecanismo comprende un alojamiento (10, 30, 40; 40), un miembro de establecimiento de dosis (50), que durante el establecimiento de dosis rota respecto al alojamiento (10, 30, 40; 40) en un primer sentido y que durante la dispensación de dosis rota respecto al alojamiento (10, 30, 40; 40) en un segundo sentido opuesto, y un elemento limitador (60) que limita el movimiento de rotación del miembro de establecimiento de dosis entre una posición de dosis cero y una posición de dosis máxima. El elemento limitante (60) es movible en un primer recorrido constreñido rotacionalmente pero desplazable axialmente con respecto a uno entre el alojamiento (10, 30, 40; 40) y el miembro de establecimiento de dosis (50) y es movible en un segundo recorrido helicoidal (53) en relación con el otro entre el alojamiento (10, 30, 40; 40) y el miembro de establecimiento de dosis (50). Por lo menos uno entre el primer y el segundo recorrido (53) tiene una parada extrema (54, 55), que limita el movimiento relativo del elemento limitante (60).This is related to a limiting mechanism that is suitable for an injection device, especially a pen-type drug delivery device. The mechanism comprises a housing (10, 30, 40; 40), a dose setting member (50), which during the establishment of broken dose relative to the housing (10, 30, 40; 40) in a first direction and which during the dispensing of a broken dose with respect to the housing (10, 30, 40; 40) in a second opposite direction, and a limiting element (60) that limits the rotation movement of the dose setting member between a zero dose position and a maximum dose position. The limiting element (60) is movable in a first rotationally constrained path but axially movable with respect to one between the housing (10, 30, 40; 40) and the dose setting member (50) and is movable in a second path helical (53) in relation to each other between the housing (10, 30, 40; 40) and the dose setting member (50). At least one between the first and the second path (53) has an extreme stop (54, 55), which limits the relative movement of the limiting element (60).
